When to Replace Spark Plugs

Your car’s ignition can’t operate without spark plugs. What do spark plugs do? They send the voltage generated by the ignition coil to the combustion chamber, which ignites as you start the car. Because your car can’t start without good spark plugs, you’ll notice right away if something is amiss. Here are a few signs replacements are needed:

• Misfiring engine
• Rough-sounding engine
• Rough noises during engine idling
• Poor acceleration
• Decreased fuel economy
• Engine startup failure or slow engine start
